Abstract
A tool for seating a tubeless tire on a rim using pressurized gas includes a cylindrical pressure tank with a nozzle affixed to it, and a rapid opening gas valve. The nozzle includes a jet configured to receive pressurized gas from the cylindrical pressure vessel into a chamber of the nozzle. As the stream of gas enters the chamber, the Venturi effect causes air to enter the chamber through air intake ports and the stream of gas and air from the air intake ports is blown out of the outlet of the nozzle. The tire is seated on the rim by positioning the system so that the air from the nozzle rapidly blows into the tire between the bead of the tire and the rim upon the valve being opened.
Claims20
A tool for seating a tubeless tire on a rim using pressurized gas, the tool comprising:
- a cylindrical pressure vessel with an input port, said input port suitable for filling the cylindrical pressure vessel with pressurized gas;
- a nozzle pneumatically coupled to an outlet on a distal end of the cylindrical pressure vessel, said nozzle configured to blow gas between a rim and a tire bead;
- a gas valve configured to control a flow of gas from the outlet on the distal end of the cylindrical pressure vessel;
- a pistol grip extending radially from the cylindrical pressure vessel;
- and
- a release control located at a position within 15 centimeters (cm) of the pistol grip;
- wherein the gas valve is configured to open in response to actuation of the release control, allowing the pressurized gas to flow through the outlet on the distal end of the cylindrical pressure vessel and out the nozzle.
The tool of claim 6, wherein the piston includes a piston ring, the piston ring positioned on the outside of the piston in close engagement with an inside wall of the cylinder;
- and
- wherein said means for filling the control reservoir comprise at least one gap in a piston ring to allow the gas to flow from cylindrical pressure vessel, through said at least one gap, into the control reservoir.
A method for seating a tubeless tire on a rim, the method comprising:
- filling a cylindrical pressure vessel with a pressurized gas to a primary pressure;
- holding the cylindrical pressure vessel by using a hand to hold a grip extending radially from the cylindrical pressure vessel to position a nozzle toward the tubeless tire on the rim, said nozzle pneumatically coupled to an outlet on a distal end of the cylindrical pressure vessel;
- positioning a rim bracket on the nozzle against a lip of the rim with a nozzle outlet positioned between the rim and the tire mounted on the rim;
- actuating a release control to open a gas valve using a finger of the hand holding the grip to allow the pressurized gas in the cylindrical pressure vessel to flow through the outlet on the distal end of the cylindrical pressure vessel to the nozzle, out the nozzle outlet to create a stream of gas, said stream of gas flowing between the lip of the rim and a bead on the tire, into the tire, causing the bead of the tire to be seated against the rim, wherein said gas valve is located inside the cylindrical pressure vessel.
